The influence of partner cues on the extinction of causal judgments in people     

Nathan M. Holmes  Oren Griffiths  R. Frederick Westbrook 《Learning & behavior》2014,42(3):289-303

Studies in laboratory animals have shown that the extinction of a conditioned stimulus, A, is regulated by the associative history of a second stimulus, X, when the two are extinguished in simultaneous compound: An inhibitory X protects A from extinction (Rescorla Learning & Behavior, 31, 124–132, 2003), whereas an excitatory X facilitates, and under some circumstances deepens, the extinction of A (Rescorla Journal of Experimental Psychology: Animal Behavior Processes, 26, 251–260, 2000, Journal of Experimental Psychology: Animal Behavior Processes, 32, 135–144, 2006). In the present study, we used the allergist task to examine whether the extinction of causal judgments in people is similarly regulated by the causal status of co-present stimuli. Experiment 1 showed that a cue trained as a conditioned inhibitor protected a target cue from extinction: The target extinguished in compound with the inhibitor was rated as being more causal of the outcome than was a target extinguished in compound with a control cue lacking inhibitory properties. In contrast, the remaining experiments showed that the extinction of a target cue was regulated by the presence, but not the causal status, of a partner cue: Target cues extinguished in compound were protected from extinction, and no evidence showed that an already extinguished partner conferred more protection (Exp. 2), or that an excitatory partner conferred any less protection (Exps. 2 and 3), or that an excitatory partner deepened the extinction of its already extinguished target. These findings are inconsistent with elemental models that rely on a common error term to explain associative changes in extinction. They are largely, but not completely, consistent with the configural model proposed by Pearce (Psychological Review, 94, 61–73, 1987), which predicts an ordering of levels of protection that was not observed.  相似文献

NEGRO TEACHERS IN NEW YORK CITY     

Daniel E. Griffiths  Others 《Equity & Excellence in Education》2013,46(1):47-48

This article addresses the question of what is entailed in enhancing teacher quality and student achievement through university-school partnership. It compares two different secondary schools working in partnership with Clark University in Worcester, Massachusetts. University Park Campus School (UPCS) is a small, neighborhood-based school that spans grades 7–12 and serves 215 students. South High School is a large comprehensive high school, with grades 9–12, and 1500 students. UPCS has attained an exceptional level of effectiveness, as reflected in student achievement; all students have passed the statewide test on their first try, with most scoring in the top two performance categories (“proficient” and “advanced”), and qualified for postsecondary education. In contrast, South High, committed to a major restructuring initiative, marks improvement more slowly and incrementally. While scale looms large as a factor in explaining the effectiveness of each school (an instrumental factor), the story of the differences between the two schools is more complex. The comparison focuses on the most salient dimensions in an effort to understand critical cultural dimensions of effectiveness.  相似文献   

Teaching Personal,Professional and Enterprise Skills in Geology     

J. S. Griffiths  W. L. Diver  C. L. Williams 《Teaching in Higher Education》2013,18(3):323-332

Abstract

Traditional vocational degrees have not always recognised the nature of contemporary post‐graduation student employment which indicates that the majority of students no longer go on to practice in a profession related to their original degree. There is a need, therefore, for such vocational degree programmes to provide a wider curriculum in commercial and industrial skills rather than just the traditional knowledge‐based teaching which is still evident in many institutions. This paper presents the basis, content, delivery and an appraisal, following 4 years of operation, of a third year compulsory module on degree programmes in geology at the University of Plymouth which aims to provide students with an introduction to the skills and practices of industry. Although the module uses geology as a focus, it could be readily adapted to a wide range of science and technology programmes.  相似文献

LEARNING TO BE IN PUBLIC SPACES: IN FROM THE MARGINS WITH DANCERS, SCULPTORS, PAINTERS AND MUSICIANS   总被引：1，自引：0，他引：1

ABSTRACT:  This article reports research in three Nottingham schools, concerned with (1) 'The school as fertile ground: how the ethos of a school enables everyone in it to benefit from the presence of artists in class'; (2) 'Children on the edge: how the arts reach those children who otherwise exclude themselves from class activities, for any reason' and (3) 'Children's voices and choices: how even very young children can learn to express their wishes, and then have them realised through arts projects'. The research methodology was rooted in two modes of inquiry, philosophical investigation and action research. The article draws on this research to argue that arts-based work in school has helped disadvantaged and/or disaffected children to engage in activities (both arts-based and others), and to be able to lay the groundwork for exercising voice and agency as they did so. If social justice is to flourish there is a need for particular kinds of public spaces and a need to create conditions such that children can learn to participate in those spaces, whether or not they are comfortable with the usual settings for 'rational argument' or 'deliberative democracy'. It is suggested that arts-based education, in some forms, is one good way of creating these conditions.  相似文献   

Primary Considerations for Primary TEFL in China     

Yvonne Griffiths 《通化师范学院学报》2007,(2):25-31

This article will focus on five key areas relating to Primary TEFL in China.Firstly,the real TEFL context in Chinese primary schools will be discussed in terms of its special characteristics.Secondly,the current methodological approach will be examined from both a theoretical perspective,focusing on government(MOE)policy for primary TEFL,and a practical perspective,based on personal observations of classroom practice.The third section of the article will highlight some perceived shortcomings of current practice,while the fourth will outline the actual needs of primary learners in the Chinese educational system.Finally,the question of how teachers can meet these needs will be examined in relation to:methodological integration; integration of skills and sub-skills teaching/learning;and the exploitation of materials and activities to provide learners with three different types of language input and output opportunities(extensive,intensive and analysed:Swan,2006).  相似文献   

The role of inhibitory associations in perceptual learning     

C. H. Bennett  V. L. Scahill  D. P. Griffiths  N. J. Mackintosh 《Learning & behavior》1999,27(3):333-345

Preexposure to two compound flavors (AX and BX) typically enhances their discriminability: An aversion conditioned to AX will generalize less to BX, especially if the preexposure regime has involved alternated presentations of AX and BX rather than presenting all AX trials before BX trials (or vice versa). One possible explanation of this finding is that alternating preexposure establishes inhibitory associations between the two unique features A and B, thus counteracting the generalization produced by excitatory associations between X and A and between X and B, which might result in either the retrieval of B on a conditioning trial to AX, or the retrieval of A on a test trial to BX. Three experiments on flavor aversion conditioning in rats tested these predictions. Experiment 1 suggested that the more important of these excitatory associations was that which allowed X to retrieve A on the test trial to BX. Experiment 2 suggested that the more important inhibitory association was that which allowed B to inhibit the representation of A on this test trial. Experiment 3 provided direct evidence of the role of this inhibitory B⊣A association.  相似文献
